CANCLIP interface fix and repair - Réparation d'interface CAN CLIP

[rgmaster3]

Here is a CANCLIP who underwent attempted repair ... he apparently had several problems including non-detection of the USB port, with one of two green LEDs off ,
and another on the multiplex network with unrecognized calculators !

So I set out to change and replace the components that had undergone attempted repair with Printed circuit tracks torn

Components were:

SJA1000T, PCA82C251 , CYPRESS AN2135SC and his quartz and two quartz 32.768kHz !

Here is the result after a good cleaning:







Several tracks on PCB are gone noticed; Chinese , we do not sit too glue that they used ? ?
So implementation of new components plus change the relay on the CAN card :

CAN electronic board :







Then reassembling the whole, connection on USB port + 12Vdc:

All LEDs light up , that's a good sign.

Installing drivers and outstanding :



Then start the clip version V136 with RSWIN software activation :
update firmware of RLT2002 probe :



then attempt to read the VIN "empty" ( ie without vehicle)



The test is quite conclusive, but let's get serious with tests on a Laguna2 ph2 (with diferent PC and V126 clip ... version ) :
Identification VIN automatic , no worries ; I get the manual box and a range of 0 and is part of a network scan and end scan ....

Message: check the integrity of the multiplexed detection and network computers 3 of 9 !



There is therefore still a big concern on this interface , but where ? ? ? ? ? ?

If we look with another probe ( always Chinese ) but it works : Here what you get on a scan of the network architecture :



On a small pattern found after on ethernet concerning the pin assignment of the OBD socket (on a megane 2) , there is high chance that the missing computers
be associated with the terminal 7 of the decision ; ie the line out ISO 9141-2 K

Let's start by looking at therefore continuity of all pinoches connector obd onto the card with the input interface connector. Here it is:



At first sight nothing special, but when you take a multimeter and test continuity; we see this video:

Incredible , no conduction immediately behind the pin round input and sounds canclip point nearest test connector ....

So I redo the weld and the other in passing.

I back all this and steering the car ; I raise the software and now i communicate with all calculators .



Still problems welding, this is crazy
